This visualization uses WebGL, which is a relatively new technology and is only supported by modern browsers. Furthermore, it uses hardware acceleration provided by the graphics card in your PC,
so you need to have a reasonably good graphics card or the display will update only slowly. You can get an idea of the speed from the frames/s value which indicates how many times per
second the display is refreshed. We artificially limit this to 30 fps, as this is perfectly adequate for this type of display.

If you cannot see the display at all, make sure WebGL is enabled on your browser, and make sure your browser is up-to-date. Internet Explorer users should make sure they have version 11
or higher. For iPad/iPhone users, please make sure you have iOS version 8 or higher, because WebGL does not seem to be supported on earlier versions.

Finally, if you want to see what the display should look like, please take a look at one of these screenshots;
